A Glencoe Classic with Jaw-Dropping Views and Serious Ridge Energy
If you’re after a big, bold day in the Scottish Highlands, it doesn’t get much more dramatic than the Bidean nam Bian ridge loop. This double Munro day combines towering crags, narrow ridges, and one of the most haunting descents in Scotland — the Lost Valley.
Located right in the heart of Glencoe, Bidean nam Bian (1,150m) is the highest point in Argyll and the crown jewel of the Glen’s south ridge. With technical terrain, steep climbs, and outrageous views, it’s a peak bagger’s dream — but one that demands proper prep and mountain experience.

Route Overview
The loop starts from the Three Sisters car park, heading up into Coire nan Lochan, a steep but scenic approach that delivers you directly onto the Bidean ridge.
From here, climb to the summit of Bidean nam Bian, take a breather, then continue east along the rocky ridge to Stob Coire Sgreamhach. The descent into the Lost Valley (Coire Gabhail) is steep and loose, but it leads to one of the most unique and atmospheric valleys in Scotland.
The final stretch brings you out of the gorge and back onto a path leading to the roadside — completing a full mountain circuit.
